Hi everyone, after much new development we finally have the adapters that give infinity focus to all those white old FD manual focus Canon super-telephoto lenses available for sale replacing the old 0.75mm adapter design.

At that price, I should buy one just in case I find a deal on a FD supertelephoto. I did not understand the bit about bending the aperture lever, but I'd figure it out quickly if I had a lens.I went back and reread the ebay listing, so I now understand the aperture lever.

If I ever am able to find a deal on a old Supertelephoto, I'll buy one of these immediately.

I found mine at a local store, Blue Moon Camera. Just lucky. It was the only FD L telephoto I've seen there. I've seen others online at eBay, henrys.com, B&H used store, and KEH.com. They pop up on Craigslist occasionally, too.

Flake

On the old system the shutter was pressed and a mechanical system operated the aperture lever to close it, now there is mention of bending the level to allow for clearance, how does the aperture stop down when needed?

The aperture lever is engaged by the adapter in either 0 degree or 90 degree orientations. The lens is stopped down by the aperture control ring on the lens and metering is strictly stop down metering since there is no motor in my adapter to do so that would be triggered by the camera electronic signal.

I've been seeing a few of this lens on ebay, they never copied the design into the EF-range, it'd be a nice big seller if they did (although the 200-400 f/4 1.4x will probably be the eventual replacement for this). The one-handed zoom/focus knob looks like a nice design touch.
